DCS Power Distribution Solution – YOKOGAWA PW482-11 S2 | CENTUM VP Series
Where This Product Is Used
The YOKOGAWA PW482-11 S2 is a dedicated power supply module engineered for mission-critical distributed control system (DCS) environments. It is widely deployed in the following industries and applications:
- Oil & Gas Refineries – Powering field controller stations and I/O bus segments in continuous process units (CDU, FCC, HDS).
- Chemical & Petrochemical Plants – Supplying stable DC power to CENTUM VP field control stations (FCS) operating in hazardous-area cabinets.
- Power Generation – Integrated into turbine control and boiler management systems requiring uninterrupted 24 VDC bus power.
- Pulp & Paper / Water Treatment – Used in redundant power architectures to eliminate single-point-of-failure risk on critical process loops.
- Pharmaceutical Manufacturing – Deployed in GMP-compliant control panels where validated, stable power is mandatory for regulatory compliance.
Wherever YOKOGAWA CENTUM VP or CS 3000 field control stations are installed, the PW482-11 S2 serves as the backbone power source for I/O modules, communication buses, and processor cards.

Application-Specific FAQ
Q: Is the PW482-11 S2 compatible with both CENTUM VP and CS 3000 systems?
A: Yes. The PW482-11 S2 is backward-compatible with YOKOGAWA CS 3000 nest architectures and fully supported in CENTUM VP R5/R6 environments.
Q: Can I run two PW482-11 S2 modules in parallel for redundancy?
A: Yes. YOKOGAWA’s CENTUM VP power architecture supports 1:1 redundant power module pairs. Both modules share the load and one can be hot-swapped without interrupting the process.
Q: What is the difference between PW482-11 and PW482-11 S2?
A: The “S2” suffix denotes a second-generation hardware revision with improved thermal management and enhanced EMC filtering. It is a drop-in replacement for the original PW482-11.
Q: Do you provide a warranty for refurbished units?
A: All units—new and refurbished—carry a 12-month warranty covering manufacturing defects and functional failures under normal operating conditions.
Q: Can Konmask supply the full CENTUM VP spare parts list for a plant turnaround?
A: Yes. Submit your BOM or tag list to support@konmask.com and our engineering team will provide a consolidated quotation within 24 hours.
